I wouldn’t trust that turbidity tube thing as obviously a sample from the top of a rad will be vastly different to one from the bottom as iron doesn’t float 😂

I’ve fitted 2 this week but I knew what was coming. I like them to be honest. Can’t go wrong for £650 inc vat

...you have to remember that there can be flaws in a brand new boiler. Dont forget that in the factory where they are put together or assembled parts maybe faulty but they will still put it on. Like for example a diaphragm might have a very thin 'needle' borehole. . Depending on the material it may need replacing immediately or gradually get worse then becomes apparent. I n a Microsoft software they forgot to put the 'Print' command. I am referring to the bracket being in the way of the rubber flue ring seal after it has been cemented . I am thinking either the bracket needs to be cut away after it's positioning has been set so the ring will be flush with the wall or the ring goes behind the bracket. Any criticism welcome. .

Vaillant said for years not to use any silicone lube on the flue seal because it damaged them. Would be interesting to know if they have changed what they are made from .The seals reacted and rippled to silicone. Have seen so many flues rotten through at an early age 👍

I fitted a lot of Glowworm and Vaillants, only fitted that boiler once and it put me off fitting another one, only a five year warranty on it as well, prefer the Worcester 1000 as a budget boiler to be honest.

I noticed you didnt trust just 2 bolts holding the boiler up either.

Ferolli make the worst boilers. We fitted 800. On contracts. Had to take the whole lot out. Total crap

Definitely give this one a miss, Alpha boilers the same with the different pipe work set up underneath, They also supply a cross over kit. Just a quick question, What does everyone use on dot & dab walls to seal the flue inside? I’ve used sand & cement but a year later when I go back to service it the sand & cement mix has usually come out 😳 I know some manufacturers like Ideal let you get away with just the internal seal so long as outside is done.

What silicone spray did you use on this video

Got to ask. The condense pipe can’t just sit in the black plastic pipe. I’ve been told in case the trap runs dry and products of combustion can leak into the room. Not me saying this Some. Mi say it.

Hi I’m looking for some advice I’m working on static caravans,their is a natural gas meter that is NOT connected to the caravan it is on a stand about a foot away from the caravan,I have been looking and looking and cannot find the legislation that states on a static caravan if the meter is not connected to the caravan it has to be on a flexi hose and not hard piped? Could you please shed some light?

Fit Baxi or if the customer wants the best Viessmann .

shouldnt they take that cost on not the customer?

Thanks Derek. Know to give this one a miss!

It’s all about ranges! They deliberately do this. Why make a £400 boiler as good as a £1000 boiler.

Just thread the collar on from the other end and it slips straight over the ridge 👍

the condensate and the PRV into the 40mm pipe are glow worm happy with that setup? As I know when I fit Ideals ect they recommend the use of a tundish for example the Hotun when combined condensate and prv into pp pipe. I have seen a few like this recently. I know the glow worm manual does say "The components must be set up in such a way that you can see the water flowing out."

Couldn’t believe they decided to change the return pipe for the mains…..thought it would be a nice easy straight swap!

What's it like ,doing some work ?

🤘😎🤘

What a load of crap...! cheap parts, poorly thought out design.... I'd love to make the designers and the accountants at Glow-work get out there and fit them...!! They'd soon scuttle off back to the office..!!

I don’t think I’ll be fitting any of those Derek , it just looks... 💩 Let’s see how it performs...!!

No worst is a the sharp ferrari quality well known piece of crap known as worcest######

another reason not to install glowworm or vaillant if you can help it. installed top of the range vaillant not long ago not impressed. plus you get the anal engineers on warranty callouts always blaming installers. how hard can it be to design a good boiler?are zee germans still sad they lost and still screwing us over? from plastic parts failing to pressure sensors designed to catch dirt. thats on bosch too. plastic hydrolic blocks failing on boilers where theres zero mention on expantion in the MI. tomcat dont get me started on alpha i see your an accredited installer. why put an lcd screen on the pcb knowing they put a shitty transformer on the same board.

I would refuse to fit that rubbish .
